'This invention relates to new am! useful improvements in faucets for the discharge or stoppage of water, steam, or gas; and

It consists in the use of an elastic oating ballvalve, which is pressed to its seat by a screw-stem or.

spindle, upon the end of which is an adjustable cone for bearing on the valve.

It also consists in a cross-har on the discharge-oriice, the whole arranged and operating as hereinafter more fully described.

In the accompanying drawing- Figure 1 represents a vertical central section of the faucet-shell, with the valve and rod arranged according to our invention.
